Norio Taniguchi (谷口 紀男, Taniguchi Norio, May 27, 1912 – November 15, 1999) was a professor of Tokyo University of Science.He coined the term nano-technology in 1974 [1] to describe semiconductor processes such as thin film deposition and ion beam milling exhibiting characteristic control on the order of a nanometer: "Nano-technology"
Japanese scientist Norio Taniguchi of Tokyo University of Science was the first to use the term "nano-technology" in a 1974 conference, [12] to describe semiconductor processes such as thin film deposition and ion beam milling exhibiting characteristic control on the order of a nanometer. His definition was, "'Nano-technology' mainly consists ...
This is a list of telephone area codes of Pennsylvania. In 1947, the American Telephone and Telegraph Company divided Pennsylvania into four numbering plan areas (NPAs) and assigned distinct area codes for each. Since 1995, several relief actions in form of area code splits and overlays have expanded the list of area
The term "nano-technology" was first used by Norio Taniguchi in 1974, though it was not widely known. Inspired by Feynman's concepts, K. Eric Drexler used the term "nanotechnology" in his 1986 book Engines of Creation: The Coming Era of Nanotechnology , which proposed the idea of a nanoscale "assembler" that would be able to build a copy of ...
The term "nano-technology" had been coined by the Tokyo University of Science professor Norio Taniguchi in 1974 to describe the precision manufacture of materials with nanometer tolerances, and Drexler unknowingly used a related term in his 1986 book Engines of Creation: The Coming Era of Nanotechnology to describe what later became known as ...
Area codes are also assigned for non-geographic purposes. The rules for numbering NPAs do not permit the digits 0 and 1 in the leading position. [1] Area codes with two identical trailing digits are easily recognizable codes (ERC). NPAs with 9 in the second position are reserved for future format expansion.
Area code 835 was eventually approved by the Public Utility Commission on December 2, 2021. Assignment of central office codes in the new area code began on September 2, 2022. [4] When area codes were introduced in 1947, their middle digit was either 0 or 1. In 1994, area code 610 was the last area code assigned with digit 1 in that position.
